Halfords autocentre in Farnborough failed my car MOT due to both rear number plate bulbs being blown. After 25 years in the transport sector I know enough about MOTs to pre-check my car beforehand (both bulbs working) and that having both bulbs fail simultaneously without a corresponding electrical fault is very unlikely. This is not the first time a car of mine had failed an MOT at this autocentre for the same reason, hence my suspicion. Standard pack of two 501 bulbs from Halfords is £3-4. Price of fitting at the autocentre without even being asked to replace them.....£20.78! Are the staff at Halfords Autocentre in Farnborough topping up their Xmas fund? My guess is I'm not the only one they're taking for a turkey!
